Pressac Sensing 60.CO2 SLR TMP HUM.868 User manual

CO2, Temperature and Humidity Sensor
Product Installation
It is recommended the Pressac Sensing CO2Sensor is installed in an environment where:
1. The local CO2level is representative of the complete area being measured i.e. do not place the unit close to
a frequently opened window or A/C unit.
2. A source of either natural or artifi cial light is available during the hours when the building is occupied (due
to the unit being solar powered).
Installation of backplate
The Pressac Sensing CO2Sensor is designed to be wall mounted. For ease of
installation it is supplied with a backplate that can be mounted on the wall
prior to installation of the CO2Sensor itself.
The backplate can be wall mounted either using the screws and rawlplugs
provided, or alternatively it can be mounted over an existing ‘pattress’ box
using the appropriate machine screws. (not provided).
Installation of unit on backplate.
BEFORE FINALLY FIXING THE SENSOR ON THE BACKPLATE, ENSURE THE UNIT HAS BEEN SET UP AND
COMMISSIONED AS PER THE PRODUCT OPERATION SECTION.
The CO2Sensor will latch onto the previously mounted backplate via the latches on the top of the unit.
Once latched, the securing screw at the bottom of the backplate can be tightened.

At a glance
The Pressac Sensing CO2Sensor is a fully wireless, solar powered room sensor, designed to measure and
report levels of Carbon Dioxide, ambient temperature and relative humidity in an internal environment. During
normal operation, the sensor is powered from ambient room light: in prolonged low light environments the
security of battery back-up ensures continued operation for over 10* years of maintenance free operation.
The sensor supports the open EnOcean® standard (ISO/IEC 14543-3-10) facilitating seamless connection with
building management systems.
Product Description
1. Selection of Sampling Rate
This can be set by confi guring DIP switch 1 as below.
2. Calibration
CALIBRATION IS ESSENTIAL To ensure accurate CO2reporting It is essential to perform a manual
calibration prior to commissioning this sensor. See section 2 of Product Operation.
Manual Calibration
To recalibrate the default level of 500ppm, set DIP Switch 3 (manual calibration) and DIP switch 4 (battery
backup) to ON and press the learn button for 5 seconds. The unit’s LED will fl ash once per second for
approximately 4 minutes. During this time, take the unit to an unoccupied environment (the ambient CO2level
here should be approximately 500ppm). After the 4 minute period, the unit’s LED will fl ash quickly for a further
2 minutes while the recalibration process takes place. Once the LED has stopped fl ashing the unit’s base CO2
level has been reset to 500PPM. Return DIP Switch 3 to the off position. Dip switch 4 can be left in the ON
position if the battery backup function is required. Moving Dip switch 3 back to the OFF position during the
procedure will abort the calibration process.

Not connected Solar powered only OFF
Connected Solar + battery powered ON
4. Commissioning
There are 2 ways in which the unit can be commissioned.
Automatic Registration.
To commission the unit, depress and release the “Learn” button. The LED will blink once. The unit now
transmits a learn telegram.
Manual registration.
Alternatively, the unit can be commissioned onto your EnOcean®network manually. To do this you will need
the unique EnOcean®ID of the Pressac Sensing CO2Sensor and also its EnOcean® Equipment Profi le. The
EnOcean®ID and the EEP are printed on the product label on the Pressac Sensing CO2Sensor.
